85' vette wipers and headlights

On my 85' corvette, Im having an odd windsheild wiper problem. They work but they dont work
What happens is, If I turn them on with the low setting, they operate just fine. But when I put it into high, they will fold down and get stuck.
It acts like it is trying to push them back out, but it won't. When it does this I have tried pulling them back out by hand, but they wont as if the motor is stuck.

If It gets stuck and I switch it back to low, then they get unstuck on there own, and work normally. Does this mean the motor is going bad?

Also another question because Im to lazy to start another thread.
On this same car, is there a way to adjust the motors on the power headlights? The problem is that when I turn them on, the drivers side will act normally and flip over. The passenger side one will flip up, but the motor will continue to try and flip it even more.
When I turn them off, they both flip back under like they are supposed to and neither motor will continue running.
I think a gear in it maybe bad, because it will not close all the way and close unevenly with the rest of the hood.

Anyone ever have either or these problems? Any ideas doc, I know this is right up your alley with corvettes and all.

Thanks
Brad

Wipers

Doc here

Check to bee sure someone didn't install the wiper blades PAST the lowest point (return, down ) on the wipers...at worst move them up 1 or 3 teeth..Also be sure both blades are in sync...that usually fixes that problem..If not let me know.

As for the Headlight doors, you should have a turnbuckle adjustment on each of the actuators, and also on the linkage rod across the air-dam...this is how you adjust door height (and limit switch height)Adjust those first closed level, and open even ... then look for an actuator limit switch on the actuators watch as you cycle the lights and adjust to stop when max open, max closed..If you can' t find limit switches they may be internal the actuator..and require repositioning of the actuator linkage.

About the headlights -- there are three plastic or nylon spacers inside the motor. These usually wear and cause problems similar to what you are describing.

Take a look at this article:

Hope this helps.

Alright, when you posted this doc I wasn't to sure on what you were talking about. I thought I could figure out what you were saying when I got out there and looked at it on the car. But after looking at it, I don't know what you meant. Could you maybe explain a little more? Thanks
Oh yeah, and I ordered the new gears for the headlights a few days ago, Ill let ya'll know how that goes.

Doc here,

Look where the wiper arms attach to the wiper linkage at the cowl..there should be a point where the arms attach to a splined driver..just remove the arm and move the arm 1 to 3 splines to the right..do the same on the other side..

Doc

Ok

Doc here,

Your Very Welcome..

Let me know if that works out, If not we'll look at the HS mode..but that usually cures the problem.
